ADVANTAGES
SAVE TIME
EASILY INSTALLED
n Installs in less than half the time of wedge anchors
or adhesive anchors
n Simply drill a pilot hole and drive the LDT anchor by
hand or impact
EASILY REMOVED
n No torching or grinding required to remove anchors
Anchor bodies are made of hardened carbon steel and zinc plated, Grade 5.
The anchors shall have a nished hex washer head with anti-rotation
serrations to prevent anchor back-out. The head of the anchor is stamped
with a length identication code for easy inspection.
The hole shall be drilled with carbide tipped hammer drill bits made
in accordance to ANSI B212.15-1994.
SAVE MONEY
LOWER DRILL BIT COSTS
n Use standard ANSI bits instead of proprietary bits
n Single piece design, no nut and washer to assemble
USE STANDARD ANSI BITS
n No special proprietary bits to purchase or lose
n Reduce chances for anchor failure due to incorrect
bit usage

LDT Anchors
APPLICATIONS
Racking, shelving and conveyors are just
a few high volume applications ideal for
Large Diameter Tapcon (L DT ™). The ease
and speed of installation of the LDT can
reduce installation time to less than half
the time of typical systems used today.
For installation speed, high performance
and easy removability, LDT is the anchor
of choice.
The LDT’s nished head and lack of exposed
threads virtually eliminates tire damage on
fork lift trucks.
FEATURES
Easy Installation
Installs into concrete by hand or impact wrench
Anti-rotation Serrated Washer
— Prevents anchor back-out
Extra Large Hex Washer Head
— With increased bearing surface
Length Identication Head Stamp
— For embedment inspection after
installation
Hi-Lo Threads
— Cuts its own threads into concrete for
greater pull-out resistance
LDT 3/8” and 1/2” are available with coating
INSTALLATION STEPS
Installation Steps for Concrete, Lightweight Concrete and Metal Deck
1. Using the proper size carbide bit (see chart)
drill “a pilot hole at least 1” deeper than anchor
embedment. “ ”
2. Using an electric impact wrench, or socket wrench
(hand install) insert anchor into hole and tighten
anchor until fully seated. (see chart for socket size)
(do not over tighten).
Installation Steps for Hollow or Grout-Filled CMU
(3/8” and 1/2” diameter)
1. Using a 5/16” (for 3/8” LDT) or 7/16” (for 1/2”
LDT) carbide tipped bit, drill a pilot hole at least
1” deeper than anchor embedment.
2. Using a socket wrench insert anchor into hole
and hand tighten anchor until fully seated.
(9/16” socket for 3/8” and 3/4” socket for 1/2”)
(do not over tighten).
LDT’s can be installed by hand or
with an impact wrench
Installation by hand—is easy, simply using
a socket wrench
Installation by impact wrench—is
recommended for faster installations
or for high volume projects. Installation
with impact wrench—is not recommended
for hollow block.
